Going off on a tangent, but still related to national cuisines, a few years ago Spanish speakers in the UK would find it hilarious how many restaurants and pubs would call their vegetarian alternative to chile con carne... wait for it... veggie con carne.

I haven't seen that term in the wild recently. I guess they eventually realised.

In the US at least it's common to refer to jus as "au jus" even in situations where the "au" doesn't make sense.

My college cafeteria would serve "beef sandwiches with au jus gravy."
